Los Angeles coroner's said the bodies were burned beyond recognition. Walker was not identified as a victim in the crash as of 10 p.m.

“We smelled the smoke and then we didn’t pay much attention to it because of the fact that this street on Friday and Saturday nights, a lot of the guys come up here with their fast cars and drift around this corner here,” said Ruben Soto, who says he was nearby at the time of the crash.

Universal Studios released a a statement Saturday evening mourning the loss of Walker.

"All of us at Universal are heartbroken. Paul was truly one of the most beloved and respected members of our studio family for 14 years, and this loss is devastating to us," the statement said.
